Understanding the Federal Per Diem System
The federal standard meal allowance is part of a larger system known as per diem, which is Latin for "for each day". This system provides a fixed daily allowance to federal employees traveling on official business to cover lodging, meals, and incidental expenses (M&IE). This approach simplifies the reimbursement process, eliminating the need for itemized receipts for every meal. While primarily used for government travel, these rates are also widely adopted by private sector companies and individual taxpayers for their own reimbursement and tax deduction purposes.
How Per Diem is Broken Down
For CONUS travel, the per diem rate is broken down into two main components: lodging and M&IE. The M&IE portion is what is commonly referred to as the federal standard meal allowance. It is designed to cover the cost of all meals—breakfast, lunch, and dinner—as well as small incidental expenses.
Examples of expenses covered by M&IE:
- All meals and non-alcoholic beverages
- Room service charges
- Tips and fees for food service and baggage handling
- Laundry and dry-cleaning services
The Two Main Methods for CONUS Per Diem
There are two main methods for determining the appropriate per diem rate for travel within the continental U.S. (CONUS), and the choice depends on an organization's preference and travel patterns. The General Services Administration (GSA) publishes the official rates annually.
1. The Standard Method
The standard method requires using specific per diem rates based on the exact locality of travel. This means the per diem rate for a trip to a high-cost area like New York City will differ significantly from a trip to a low-cost area. For businesses with varied travel destinations, this method offers the most precise reimbursement, as it accurately reflects the cost differences between locations. The GSA website (GSA.gov) provides a lookup tool for determining the exact rate by location.
2. The High-Low Method
For companies with consistent travel patterns or a desire for administrative simplicity, the high-low method is an effective alternative. The IRS sets two rates annually: one for designated "high-cost" localities and a lower, single rate for all other areas within CONUS. For the 2025 fiscal year, the IRS designated rates are higher for high-cost areas and lower for all others. This approach reduces the complexity of looking up individual city rates but may not be as precise for specific travel locations. Self-employed individuals, however, are typically required to use the standard method for claiming deductions.
The M&IE-Only Option
For day trips or situations where lodging is not required, the M&IE-only rate is used. This rate is simply the meal and incidental portion of the full per diem rate. For example, for the fiscal year 2025, the standard CONUS M&IE rate is $68. In high-cost areas, the M&IE-only rate is higher. The 75% rule also applies on the first and last day of travel, regardless of departure or return time, for the M&IE portion of the rate.
Using the Standard Meal Allowance vs. Actual Expenses
When reimbursing for travel, businesses and individuals have the choice of using either the federal standard meal allowance or tracking actual expenses. Each method has its pros and cons, which can impact administrative workload and tax deductions.
| Feature | Standard Meal Allowance (Per Diem) | Actual Expenses Method |
|---|---|---|
| Administrative Burden | Significantly lower; no need to collect and verify meal receipts. | High; requires detailed tracking and retention of all meal receipts. |
| Record-keeping | Requires proof of time, place, and business purpose of travel, but not meal receipts. | Requires itemized receipts for all meal expenses. |
| Reimbursement Amount | Fixed daily rate, regardless of how much was actually spent. Can lead to over- or under-reimbursement. | Direct reimbursement of the exact amount spent on meals (subject to caps). |
| Tax Implications | Non-taxable to the employee if the reimbursement is at or below federal rates. | Non-taxable if reimbursed under an accountable plan, with proper records. |
| Application | Widely used by private companies for employee travel; self-employed individuals can only use for meals. | Often used when actual costs are expected to be significantly higher than the per diem rate. |
The Annual Update Cycle and Rate Changes
Federal per diem rates, including the meal allowance, are updated annually to reflect changing costs of living. The new rates typically take effect at the start of the government's fiscal year, which is October 1st. Travelers and businesses should always check the General Services Administration (GSA) website or the relevant IRS guidance for the most current rates applicable to the travel dates. Staying informed about these updates is crucial for accurate reimbursement and tax purposes, especially given recent increases.
For example, the M&IE portion of the standard CONUS rate increased from $59 to $68 for the 2025 fiscal year, representing a significant change for travelers and their employers. Staying current with the federal standard meal allowance ensures proper reimbursement and simplifies expense reporting for both employers and employees.

Conclusion
The federal standard meal allowance is a fundamental tool for managing and deducting business travel expenses. By providing a fixed, simplified daily rate for meals and incidental expenses, it reduces the administrative burden associated with tracking every minor cost. Whether using the location-specific standard method, the high-low method for streamlined processing, or the M&IE-only rate for day trips, understanding these allowances is key for both employees seeking tax-free reimbursements and businesses aiming for simplified expense management. With annual rate adjustments, particularly noticeable changes like those for the fiscal year 2025, keeping abreast of the latest information from the GSA and IRS is essential.
